Need help with design ideas

[nyx~]

I've done basically every kind of "themed" area you can do I'm the game, and I still have room that idk what to do with. I desperately need design ideas before I make ANOTHER cafe lol.
These are areas I have:
-Crafting/Tool Shed Area
-Space Area
-Rainbow Flower Garden
-Pool
-Wedding Area
-Spa
-Gym
-Carnival
-Cafe
-Playground
-Orchard
-Picnic/BBQ Area
-Bamboo Forest
-Fountain Plaza-like Area
-Shell Area (on hidden beach)

I was planning on doing a pirate or mermaid area on the beach once I get more furniture, so anyone have any other ideas? I'm stuck.

Maybe some type of market? Flower market, or food, or items, clothes?
